because if they don't they will be slowly assimilated into a non-democratic PRC. I am not calling for independence, I'm saying it would be nice if they had it rather than add 7m people to a regime.

they wouldn't, that's the point.
If HK were to declare independence, in other ages there might have been foreign powers propping them up _for their own interests_. I am not advocating this, I'm just pointing out this seems unlikely in the current world.
As for the Seattle independence: well, HK was independent for a while, and they hare already a SAR, the simile seems incorrect, but sure, it's not trivial to secede.
